System management partly comprises signals collecting terminal A, device processes terminal B, display terminal C and management server D, and wherein, each device processes terminal B and management server D are connected with signals collecting terminal A by communication network E.
Import and export setting pressure transmitter 6 at every screw air compressor 1, air pressure surge tank 10, oxygen pressure surge tank 13, hyperbaric oxygen gas storage tank 20, air-separating oxygen-making machine 12; Outlet at freeze drier 5 is equipped with temperature transmitter 7; Prime accurate filter 4, intermediate accurate filter 8A, back level accurate filter 8B and sterilizing filter 15 4 set filters all are provided with the differential pressure transmitter 9 that detects its inlet outlet pressure differential.In addition,, purity instrument 17 is installed also on the oxygen house steward, sterilizing filter 15 and flow transmitter 16 are installed on each bar oxygen manifold in order to ensure the quality and the gas supply flow of oxygen.Omnibus bar 14 standby when supplying air-separating oxygen-making machine system overhaul is installed on exporting the oxygen manifold road in ward to; Exporting installation oxygen supercharger 19 and hyperbaric oxygen gas storage tank 20 on the oxygen manifold road of Hyperbaric oxygen chamber to.
In the air-separating oxygen-making process, air passes through screw air compressor 1, prime accurate filter 4, freeze drier 5, intermediate accurate filter 8A, back level accurate filter 8B, air pressure surge tank 10, air-separating oxygen-making machine 11, oxygen pressure surge tank 13, sterilizing filter 15, sub-cylinder 18 successively, oxygen supercharger 19, behind hyperbaric oxygen gas storage tank 20 and the oxygen reducing valve 21, be delivered to ward or Hyperbaric oxygen chamber by each oxygen manifold road.
The utility model system is when work, at first, pressure, the flow signal of pneupress system fed back to the input terminus of the variable frequency adjustment device 2 (every air compressor one) of screw air compressor 1, be the run signal that is converted to motor after its assignment and drive parameter (as rotating speed, voltage, electric current etc.); By primary instruments such as pressure unit 6, temperature transmitter 7, pressure difference transmitters 9, follow the tracks of the instant variation that detects each parameter, and with aforementioned transmitters sense to each analog signal conversion be numerary signal, after by multiplexed signal sampling terminal A (also can adopt GPRS intelligent acquisition terminal) these signals being gathered, caught, the analog simulation and the real time data of carrying out field working conditions show.Again by device processes terminal B (with the data that collect and set(ting)value (as pressurized air or oxygen system pressure, the isoparametric upper and lower limit alarming value of freeze drier temperature out) analyze, relatively (phase detected signal), control opening, stop or switching of power elements such as relevant device and valve automatically by " output is controlled " again.In addition, these operational processs and the status data of equipment, display terminal C and device processes terminal B have also been passed to simultaneously, carry out reading, record, printing, digital transmission or the like, and write down and preserve in modes such as real-time and historical chart data and real-time history curves, with convenient system carried out intellectual analysis and for future reference with history run situation and warning reason at random.
Below illustrate principle of work of the present utility model fully with three unit air-separating oxygen-making systems dual-purpose: if operating two covers have in the units operating parameter of an equipment or a cover system to hinder for some reason and have departed from set(ting)value (be higher than higher limit or be lower than lower value); system just sends guard signal; automatically cut off the fault unit by above-mentioned " output control "; start the standby unit of the 3rd cover simultaneously, power elements such as the related valve of system are also opened thereupon, are stopped or switching.When causing shutting down if catastrophe failure appears in field apparatus, system can send warning signal, the running status that the prompting user checks field apparatus, and can carry out the safeguard protection operation automatically; Even the system of making and equipment can not cause accident or damage yet under the state of fault; Finish dealing with the back by the confirming button close box.Perhaps when system parameter returned to normal value, alarm can be eliminated automatically.
If be lower than set(ting)value (for example 93%), system just sends guard signal when the purity of oxygen and flow, and operator just can regulate the operating panel and the controlling elements of air separation oxygenerator according to fault characteristic; What the differential pressure transmitter 9 of each link strainer showed is the random variation of pressure reduction before and after the strainer, if this pressure reduction has trend of rising, illustrates that then strainer has the sign of obstruction, just the system alarm device can send guard signal when rising to upper limit setting; If this pressure reduction has obvious downtrending, the strainer breakage is described, when being low to moderate lower limit set value, system also can send guard signal; Equipment management personnel just can be judged the filter failure situation in trend according to the change of differential pressure before and after the strainer, so that when strainer has damaged tendency, just remove to check, clean or change the filter core of strainer, avoid oxygen and delivery system thereof to be polluted, or influence the breakage of the gas supply flow and the quickening filter core of system because of the obstruction of filter core because of the breakage of filter core.
In addition, monitor simultaneously for ease of a plurality of departments, can join exchange board and Duo Tai display terminal C, and can in machine room, add camera and wireless accurate image and data transmission terminal so that air-separating oxygen-making machine room and status of equipment are carried out conduct monitoring at all levels, by GPRS or CDMA1x wireless network, the video flowing of high quality, and get off by the hard disk recorder of administrative center or by long-range video record.Simultaneously, the maintenance service personnel also can open main interface by the internet, carry out remote monitoring and inquiry at any time, and carry out fault judgement and processing by phone or video frequency remote-control guides user; By corresponding configuration software with IE browses or the FTP access, carry out center monitoring management and remote monitoring and administration easily.
Certainly, above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to the foregoing description, those of ordinary skill in the field are to be understood that, still can make amendment or be equal to replacement embodiment of the present utility model, and do not break away from any modification of the utility model spirit and scope or be equal to replacement, it all should be encompassed in the claim scope of the present utility model.
